Many service providers are now providing applications on the Web that encourage people to satisfy information needs on the Web. The proposed research attempts to investigate the usage and evaluation of these Web-based information services by providing some initial efforts toward developing conceptuallybased scales for evaluating the extent to which Web services satisfy information needs that arise outside the traditional organizational/work domain. The emphasis on non-work based tasks allows the research to focus on the use of the Web in satisfying information needs that arise outside the work-place/task domain. Three streams of literature are considered: usage of the Web, user satisfaction of the Web, and the complementary field of individual performance and the impact of information technology. Based on these foundations, as well as focus groups and pilot surveys, questionnaire items were developed and analyzed across three surveys for their dimensionality and reliability of scales measuring access, usability, task-technology fit, social influences and individual performance impacts. This paper reports the results of the final Web based survey which generated 720 responses. Predictors of performance included the following scales: training (developing Web skills), fun/entertainment, years of overall computer experience, mediation (shopping cost), greater weekly usage.
